Embodiment 1
[0024] A processing method for a blank-holder sheet metal part, comprising the following steps:
[0025] Step (1): punching the metal plate through a punching device to obtain the plate body of the edge-pressed sheet metal part;
[0026] Step (2): after completing step (1), grind the edges and corners of the plate body to remove burrs, clean the outer surface of the plate body, and remove iron filing impurities on the surface;
[0027] Step (3): put the plate body into the punching device, limit it, open the punching device and start punching the metal plate;
[0028] Step (4): After finishing step (3), add an appropriate amount of pure water to the cleaning tank, add buffer solution and corrosion inhibitor to the pure water to obtain cleaning water with a pH of 5 to 6, and wipe the sheet metal parts with a wiping cloth ;
[0029] Step (5): Arrange the sheet metal parts neatly in the basket, first put them into the degreasing tank equipped with degreasing liquid, and make th...

The invention discloses a processing method of a blank pressing sheet metal part, and relates to the field of sheet metal part processing. A method for machining a blank-pressed sheet metal part comprises the following steps that (1) a metal plate is blanked through a blanking device, and a plate body of the blank-pressed sheet metal part is obtained; (2) after the step (1) is completed, corners of the plate body are polished, burrs are removed, the outer surface of the plate body is cleaned, and scrap iron impurities on the surface are removed; and (3) the plate body is put into a stamping device to be limited, and the stamping device is started to start stamping the metal plate. During stamping, the outer surface of the sheet metal part is flushed through a high-pressure water gun, the water pressure is not smaller than 18 MPa, scrap iron and sticky hard impurities on the outer surface can be cleaned, so that the smoothness of the outer surface of the sheet metal part is guaranteed, the situation that the sheet metal part is concavely and convexly distributed due to the scrap iron during stamping is avoided, and the stamping quality is improved. And the quality and the aesthetic property of the sheet metal part are improved.
Description
technical field [0001] The invention relates to the field of sheet metal part processing, in particular to a processing method of a blank-holder sheet metal part. Background technique [0002] Sheet metal is a comprehensive cold working process for thin metal plates, including shearing, punching / cutting / compounding, folding, welding, riveting, splicing, forming, etc. Its remarkable feature is that the same part has the same thickness and is processed by sheet metal technology. The products are called sheet metal parts. The sheet metal parts referred to in different industries are generally different, and are mostly used for assembly. When the sheet metal parts are pressed, a special device is usually used for edge pressing. [0003] The existing equipment that specializes in blanking sheet metal parts needs to cut and grind the sheet metal parts before blanking the sheet metal parts. After cutting and grinding, iron filings will be generated. At the same time, when cleaning...
